Definitions
- the present invention is directed to an unsymmetrical infeed plate for directing harvested crop to an axial flow rotor.
- Agricultural combines are large machines that harvest, thresh, separate and clean an agricultural crop.
- the resulting clean grain is stored in a grain tank located on the combine.
- the clean grain can then be transported from the grain tank to a truck, grain cart or other receiving bin by an unloading auger.
- Axial flow combines have one or two large rotors arranged along the longitudinal axis of the machine for threshing and separating the harvested crop material.
- Harvested crop material is directed to the axial rotors by a feederhouse.
- Most feederhouses transport the harvested crop in a thin mat extending across the width of the feederhouse.
- transverse upstream section of the infeed plate is provided with a conical section and the transverse downstream section is provided with a curved ramp.
- the ramp is provided with an upwardly extending rim.
- Harvested crop from the feederhouse is directed to a transverse beater which propels the crop material across the infeed plate to the axial rotor.
- the rotor is rotated counterclockwise when viewed from the front of the combine.
- the left side of the infeed plate when viewed from the front of the combine comprises a transverse upstream section of the infeed plate, and the right side comprises a transverse downstream section. If the rotor was rotated clockwise these sections would be reversed.
- harvested crop material propelled up the transverse upstream section of the infeed plate is curled towards the rotor and is primarily directed to the bottom of the rotor by a conical section. Crop material propelled up the transverse downstream section is directed up by a steeper curved ramp to the top of the rotor.
- the unsymmetrical configuration of the infeed plate introduces the crop mat to the axial rotor so that it is more easily rotated by the rotor and taken into the rotor housing.
- the ramp is provided with an upwardly extending rim.
- the rim forms a shallow zone in its shadow.
- Harvested crop material located in this zone is allowed to slide up a semi-cylindrical plate to feed the rotor.
- the rim substantially limits the movement of crop material laterally across the infeed plate. More specifically the counterclockwise rotation of the rotor tends to drive the crop material to the transverse downstream section of the infeed plate. The substantially reduces this tendency in the crop mat. As such the rim provides for a more uniform loading of the rotor.
- the infeed plate forces the crop material into one of three flow paths. Each flow path introduces the crop mat to different sections of the rotor, thereby more uniformly loading the rotor. That portion of the crop mat on the transverse upstream side furthest to the outside is forced into the conical section and up the adjoining sidewall and is introduced to the bottom of the rotor. The portion of the crop mat in the middle of the infeed plate flows up the semi-cylindrical plate to the side of the rotor. The crop material furthest to the outside on the transverse downstream section flows up the ramp and the oblique curved ramp and is introduced to the top of the rotor. The three streams more evenly introduce the crop mat to the rotor.
- FIG. 1 is a semi-schematic side view of an axial flow agricultural combine.
- FIG. 2 is a perspective view of the infeed plate of the present invention.
- FIG. 3 is a top view of the infeed plate.
- FIG. 4 is a front view of the infeed plate.
- FIG. 5 is an side view taken along line 5--5 in FIG. 4.
- FIG. 6 is a cross sectional view taken along line 6--6 in FIG. 4.
- FIG. 1 shows an agricultural combine 10 comprising a supporting structure 12 having ground engaging means 14 extending from the supporting structure.
- a harvesting platform 16 is used for harvesting a crop and directing it to a feederhouse 18.
- the harvested crop is directed by the feederhouse 18 to a beater 20.
- the beater directs the crop upwardly through an inlet transition section 22 to the axial crop processing unit 24.
- the crop processing unit threshes and separates the harvested crop material. Grain and chaff fall through grates on the bottom of the unit 24 to cleaning system 26.
- the cleaning system 26 removes the chaff and directs the clean grain to a clean grain elevator (not shown).
- the clean grain elevator deposits the clean grain in grain tank 28.
- the clean grain in the tank can be unloaded into a grain cart or truck by unloading auger 30.
- Threshed and separated straw in discharged from the axial crop processing unit through outlet 32 to discharge beater 34.
- the discharge beater in turn propels the straw out the rear of the combine.
- the operation of the combine is controlled from operator's cab 36.
- the axial crop processing unit comprises a cylindrical rotor housing 38 and a rotor 39 located inside the housing 38.
- the rotor housing has a top portion 40 and a bottom portion 42. The bottom portion is provided with grates through which grain and chaff fall to the cleaning system.
- the rotor housing and the inlet transition section are positioned between the sidesheets 44 of the combine. The sidesheets forming part of the supporting structure of the combine.
- the inlet transition section 22 is best illustrated in FIGS. 2-6.
- the front portion of the rotor projects into the inlet transition section.
- This section comprises an infeed plate having two sections: a transverse upstream section 46 and a transverse downstream section 50.
- the transverse upstream section is provided with a conical section 52 which starts curling the thin mat of harvested crop material and introduces the crop layer on that side of the infeed plate to the bottom of the rotor.
- the beater propelled crop layer on the transverse upstream side runs along an inclined plate 54 until it contacts the conical section 52.
- the inclined plate extends from the transverse beater to the conical section.
- a triangular converging side plate 56 and a horizontal triangular top plate (not shown) further constrain the flow of the crop material to the rotor.
- the transverse downstream section is provided with a curved ramp 58 that curves upwardly towards the rotor.
- the curved ramp is steeper than the inclined plate 54.
- a semi-cylindrical plate 60 which essentially forms part of the rotor housing.
- the crop mat is further constrained by oblique curved ramp 62 that is mounted between ramp 58 and planar side plate 64. Crop material along the outside edge of ramp 58 is thrown up ramp 58 by the beater and engages oblique ramp 62 which throws the crop material on top of the rotor.
- the ramp is provided with an upward extending rim 66 that forms a shallow dead zone behind the ramp. Crop material trapped in this zone slides up the semi-cylindrical plate 60 and is transported to the rotor.
- the rim 66 also keeps crop material in section 46 from mixing with crop material in section 50.
- the rim In addition to providing this shallow dead zone behind the ramp, the rim also substantially limits the movement of crop material, propelled by the rotor from moving from the transverse upstream section to the transverse downstream section.
- the present invention provides a passive system for efficiently introducing a thin crop mat to an axial crop processing unit. As such it should not be limited by the above-described embodiment, but should be limited solely by the claims that follow.
